Termineter – Smart Meter Security Testing Framework



Termineter is a Python Smart Meter Security Testing framework which allows authorised individuals to test Smart Meters for vulnerabilities such as energy consumption fraud, network hijacking, and more.

Termineter - Smart Meter Security Testing Framework

Many of these vulnerabilities have been highlighted by the media and advisories have been sent out by law enforcement agencies. The goal of a public release for this utility is to promote security awareness for Smart Meters and provide a tool that brings basic testing capabilities to the community and meter manufacturers so that security can be improved.

Power companies can use the framework to identify and validate internal flaws that leave them susceptible to fraud and significant vulnerabilities.

How it Works

Terminter utilises the C1218 and C1219 protocols for communication over an optical interface. Currently supported are Meters using C1219-2007 with 7-bit character sets.

This is the most common configuration found in North America. Termineter communicates with Smart Meters via a connection using an ANSI type-2 optical probe with a serial interface.

Users must have general knowledge of the meter’s internal workings in order to use Termineter proficiently.
